So... you say you want to give Brikwars a nice 10 point rating, but you can't figure out which button to click. I feel your pain. That site is a mess.

6 First set up an account
7 Go to the Brikwars page
8 Go to the bottom of the page ( yeah not the top near the rating as you would expect)
9 User Information > Add a copy to your collection (click that)
10 You will see " Rating N/A" (click on the N/A, that was intuitive right?)
11 Enter your rating in the box

I figured that out by accident, good thing I'm 6 feet tall.

If the game gets rated 30 times it will enter the overall rankings and will show up on other lists of ranked games. Just 2 more to go.
